because the water is a liquid and air is a gas. so you can hear way clearer in the air because it wanders around and when it's in water it doesn't.it's like a solid but absorbs the sound
Sound waves travel faster in water than in the air and their is less attenuation (loss of loudness) for the same distance traveled so it sounds differently to the ear where we re used to hearing noises through air. Also their may still be some air in the ear canal and the sound waves switching from water to air (in the ear) to the ear drum can result in distortion.
Because water conducts sound waves much better than air does.
Sound moves faster and further in water than air, so it would seem like it must have something to do with the receiver. I'm guessing, but I'd guess it's because the eardrum evolved to hear sounds in air. Underwater you don't hear using the eardrum, you hear by way of bone conduction which apparently doesn't let you hear normal sounds as well as the air/eardrum method.
low frequency
Loud speakers can produce ultrasonic waves. But since the normal purpose of loud speakers is to produce sounds for people to hear, there is seldom a reason to produce sounds that people can't hear (other than to annoy certain animals).
Solids will transmit sound waves, some better than others. Therefore you can hear through some, though it depends on the material and thickness.
because air is thiner and water has monicules

Yes there are high pitched sounds that teenagers can hear that teachers cannot hear
Wolves can hear better than humans.
Whales can generally only hear sounds that are made underwater. They have very good ears, because they 'talk' to each other using grunts and squeals over long distances. Sound waves travel extremely well in water . . . much better than in the air.
Sounds, which are nothing more than vibrations, can actually be heard better and further underwater than in air. So I would think frog's ears would be useful both underwater and sitting on land, to detect noise/vibrations of predators and to detect mates.
I live on a lake and swim quite often. When you go underwater and a boat goes by a 1/4 mile away, you can distinctly hear the prop and engine whirring. Also, the boat sounds much closer and louder than it does above water because sound travels better in water than in air. This is because it is more dense than air.
different animals have different improved scenes like dogs have a better scene of smell they we do.. it because of the environmental the animal lives in. Dolphins communicate my sound and sound is harder to hear underwater so they have improved hearing.
As a hunter, dogs have evolved to have better hearing than humans. They can even hear voles/lemmings scurrying round under the snow!!
Both whales and elephants can hear extremely low frequency sounds.
They can hear more, but not better. Because of the density of water, vibrations are changed in pitch, and may be muffled and garbled. Since clarity is the most important factor in hearing, underwater communication is mostly done by hand signals instead. On the other hand, sound moves more quickly underwater, and as a result you can hear from a greater distance. Things can be heard from a lot further away and/or are louder than in air. Unfortunately, because of the higher speed, and reflections from the bottom, sound direction is almost impossible to determine by ear.
